(6R) - 4,5,6,7 - tetrahydro - 1,3 - benzo dioxin - 2,6 - diol, this substance has the following chemical properties:
Its molecular structure contains phenolic hydroxyl groups, which give it a certain acidity. The hydrogen atoms in the phenolic hydroxyl group are more active and can react with bases, such as with strong bases such as sodium hydroxide, to produce corresponding phenolic salts and water. For example, when it reacts with sodium hydroxide, the hydrogen atoms on the phenolic hydroxyl group are replaced by sodium ions to form (6R) - 4,5,6,7 - tetrahydro - 1,3 - benzo dioxin - 2,6 - diphenol sodium salt.
Due to the existence of the benzene ring, it can undergo electrophilic substitution reaction. The electron cloud density on the benzene ring is high, and it is easily attacked by electrophilic reagents. For example, under appropriate conditions, bromination reaction can occur with bromine water, and bromine atoms replace hydrogen atoms on the benzene ring, mainly generating phenolic hydroxyl-ortho and para-site bromogenic products.
The substance may also undergo oxidation reaction. The phenolic hydroxyl group is easily oxidized, and it may gradually be oxidized and discolored when placed in air. If it encounters stronger oxidants, such as potassium permanganate, the phenolic hydroxyl group may be further oxidized to quinones and other products, causing major changes in its structure and properties.
In addition, given the multiple oxygen atoms it contains, under suitable conditions, it has the potential to act as a ligand to coordinate with metal ions to form complexes, which can have a significant impact on its physical and chemical properties.

The synthesis method of (6R) -4,5,6,7-tetrahydro-1,3-benzodioxane-2,6-diol, although there is no modern concept of precise organic synthesis in the era covered by "Tiangong Kaiwu", the wisdom of the ancients can also be used for reference.
In the past, if you want to make this product, you can start with natural products containing similar structures. Such as many plants and trees, some of their components may have this structural fragment. At that time, craftsmen may have repeated cooking and extraction methods. First extract suitable plants and trees, place them in a kettle, use water as a medium, and cook for a long time. This is a method of dissolving useful ingredients with water such as sugar and salt in "Tiangong Kaiwu". After cooking, some of the plants and trees containing similar structural substances are dissolved into water, and then the residue is filtered off with a fine filter or gauze to obtain a crude liquid containing the target ingredient.
After that, evaporation and concentration are performed. According to the method of boiling and purification described in "Tiangong Kaiwu", the crude liquid is placed in an open container and heated at a moderate heat. The water vapor gradually dissipates, and the concentration of the solution gradually increases. During the process, the heat and time should be carefully controlled. If the heat is too fierce, the ingredients may be damaged; if the heat is insufficient, the concentration effect will not be good.
Furthermore, or by recrystallization to improve the purity. To be concentrated to a certain extent, cool the solution. Due to the decrease in temperature, the solubility of the target ingredient changes, and the crystallization precipitates first. At this time, it is necessary to carefully separate the crystals from the mother liquor, or use special tools to remove the crystals, and then rinse with a small amount of cold water to remove surface impurities.
Although there were no modern accurate instruments and theories in ancient times, through such empirical methods, after repeated attempts and exploration, a small amount of (6R) -4,5,6,7-tetrahydro-1,3-benzodioxane-2,6-diol can be obtained. The process shows the wisdom and skills of the ancients in material extraction and purification.
